Hello everybody. This is my first post, and my second project with my new AR8. I'm still getting a feel for it, but this project turned out pretty good. I plan to make these smaller in the future so it doesn't take as much machine time. This set is 24" wide, the next set will be 18. That will cut the machine time down from 6 hours to 4 hours. I used a 1/4 inch end mill for the rough cutting, and a 1/8 ball nose for the finish. The phoenix was cut out separately and glued later...mainly for ease of painting. It was cut with a 1/16 inch tapered 5.4 degree round nose. Finally I used an engraver bit for the lettering. I'll be posting the smaller set soon to follow.  |

So, since the first set of wigs I've been busy. Right now I have a backlog of people wanting these wings. I have made two sizes now 18" and 24" The 18" take about 1 hour a piece of machine time with a 1/8th ball nose. The 24 take about 3.5 hours. They are all made out of oak and then the phoenix in the middle is maple (had to use a denser wood due to the fine detail in the beak and the wings). I have also added a wreath to the options people can get. I wasn't expecting these to be that popular, I guess you never know what will take off and what won't. Also I think my wife has a project that snuck into the picture if you guys see that coaster to the right of the wings. Attachments:

Really nice. Looks like I should try a 3D project with the 1/8" ball nose vs the 1/16" I used. Should be a major time reduction right there. 3.5 hours for that 24" piece is great. You've really optimized things very well!

Depending on your feedrates, you may be able to adjust further. On larger 3D carvings we use a 1/8" tapered ball, we almost always run at 200ipm for finishing.

Yup, I run the 1/8th right now at 24000 rpm and 200 ipm feed rate the calculator off cnc cookbook helped me determine it. That's one of the reasons I got the speed up as fast as I did. Thanks for the input though, from now on I'll try to include the tool settings with the description so others can build up their tool database. |

Those look great! How did you figure out how much to charge for them?

Ultimately I charged the same price as the previous lithos we used to give a going away gifts, even though I could probably get a little more, I essentially charge 30 dollars an hour including machine time and my hand finish time afterwards.
